Rank speed of absorption: Po, IM, IV - Answer-Po slowest, then IM, IV fastest Describe drug distribution in relation to protein binding - Answer-Protein binding- Most drugs form a compound and bind with plasma proteins. Drug molecules bound to plasma proteins are pharmacologically inactive. Only the free or unbound portions of the drug acts on the cells. Protein binding allows for some of the drug to be stored and others to be released as needed. This gives the constant blood level and decr...

Saturable transport in intestinal mucusa will (increase/decrease) bioavailability decrease If a drug is comparatively insoluble it will (increase/decrease) bioavailability decrease If a drug is saturable during hepatic metabolism on first pass it will (increase/decrease) bioavailability increase If a drug has saturable plasma protein binding it will (increase/decrease) volume of distribution and fraction unbound increase If a drug is actively secreted it will (inc...

Katzung & Trevor's Pharmacology: Examination and Board Review INTRODUCTION 1. A 3-year-old is brought to the emergency department having just ingested a large overdose of tolbutamide, an oral antidiabetic drug. Tolbutamide is a weak acid with a pKa of 5.3. It is capable of entering most tissues, including the brain. On physical examination, the heart rate is 100/min, blood pressure 90/50 mm Hg, and respiratory rate 20/min. Which of the following statements about this case of tolb...
